ROPE-DRUM ENGINE.

SPECIFICATION forming part of Letters Patent No. 765,659, dated July 26, 1904.

Application filed January 13, 1904. Serial No. 188,851. (No model.)

To all whom, it may concern:

tion in one form. Fig. 2 is aside view of the.

same. Figs. 3, 4, 5, and 11 are details thereof. Figs. 6 and.7 are a plan and side view of another form. Figs. 8, 9, and are details thereof. Fig. 12 is a modified form. Figs. 13 and 1 1 are details of another modification.

I will first describe the hoisting -engine proper, which is of substantially the same construction in all forms shown and which for clearness is in Figs. 1 and 6 drawn in finer lines than the swinging-gear annex.

1 is the hoisting-engine bed-plate. I 5 is the boiler.

6 represents the cylinders, and 7 the crankshaft, of the engine. eccentric-rods are omitted from Fig. 1.

8 and 9 are two hoisting-rope drums, one

of which is employed for operating the rope to hoist the boom of a derrick and the other to operate the rope that hoists the load. and 11 are the shafts upon which said drums run loosely.

12 is a friction band-brake operated by the foot-lever 13 for controlling the drum 8, and 14 is a friction baud-brake operatedby the foot-lever 15 for controlling the drum 9.

16 represents ratchet-teeth on the drum 8, engaged by a dog 17. 18 represents similar ratchet-teeth on the drum 9.

19 is a pinion on the engine crank-shaft which drives the spur-wheels 20 and 21, fixed on the drum-shafts 10 and 11, respectively. Any suitable friction-clutch is interposed between the spur-wheels 2021 and their respective drums 8 and 9. 22 and 23 are the handlevers by which the friction-clutches of each drum are set.

24 is a winch-head fixed to the end of shaft 10 outside the pillow-block.

. the end of shaft 11.

The connecting-rods and.

25 is a corresponding winch-head fixed to 26 and 27 are the pillowblocks of the hoisting-engine.

I have shown the swinging-gear annex in two forms, respectively, in Figs. 1 to 5'and 6 to 9. I will first describe those features in which the two forms are alike: 30 is a shaft upon the outer ends of which outside the pillow-blocks are loosely mounted the drums or heads 31 and 32, on which the opposite ends of the swinging or bull-head rope are inversely coiled. Engaging each of these drums is a clutch 33, splined to the shaft 30 and held in engagement with its drum by a plate 34, held by jam nuts 35. By loosening these jamnuts the teeth of either clutch may be disenion 38 is driven by'a pinion 4E2, fixed to a 64: and 65 are The pinions 4:0 and friction-clutch member 13. collars on the shaft A l.

.42 and their connected clutch members ll 43 are revolublygloose on the shaft .91 and are driven. therefrom through the friction-clutch members 45 and 46, splined thereto.

Two means are shown for setting the clutch members 45 and 46. I will first describe the means shown in Figs. 1 to 5, wherein. the clutch member 45 is set by the rotation of the collar 4&7 on the collar 48, which is held from rotation by the bracket L9 and held from longitudinal movement bythe divided collar 50, said collars 47 and 48 being provided with cooperating cam faces 47 and 4:8. The clutch member 16 is set by the rotation of collar 51 on the collar 52, which is held from rotation by the bracket 53 and from longitudinal movement by the divided collar 54L, said collars 51 and 52being provided with cooperment-gear 56 on the shaft 57. The cam 51 carries a segment-gear 58, driven by the segment-gear 59 on the shaft 57, which is operated by the hand-lever 60. Thus the forward movement of this hand-lever throws one friction in and the other out. The backward movement reverses this operation. When the lever is in an upright position, neither friction is engaged.

In the construction shown in Figs. 6 to 10, which is the one I prefer, in lieu of thecamfaces47 48 and 51 52 for separating the collar 47 from 48 and 51 from 52 I substitute the following construction: is a brass or composition sleeve loose on the shaft, but fixed to the collar 48 and projecting inside the collar 47, which is screw-threaded thereon. 71 is a clamp on the outside of the collar 47 and oscillated from the shaft 57 by the arm 72 and link 7 3. Similarly 74 is a sleeve fixed to the collar 52 and projecting inside the collar 51, which is screw-threaded thereon, and 75 is a clamp on the outside of collar 51, which is oscillated from the shaft 57 by the arm 76 and link 7 7 The screw-threads of the sleeves 70 and 74 are pitched to produce inverse operation. By loosening the clamp 71 or 75 and moving the collar 47 or 51 therein and then tightening the clamp either friction may be adjusted to take up wear.

I prefer to drive the shaft 44 from the shaft 11 by the gears 78, 79, and 80. although the sprocket-chain 81 and wheels 82 83 may be employed, if desired, for the same purpose.

For the purposes of operation the operator stands Within reach of the three hand-levers 22, 23, and 60 and the two foot-levers 13 and 15. It is thus within his power to placeeither of the hoisting-drums 8 9 under either a driving friction or a brake friction and to place the swinging drums 31 32 under a driving friction in one direction or a driving friction in the other direction or in neither direction. Thus without leaving his position the operator has complete command of the derrick both with respect to the hoisting and lowering of the boom, the hoisting and lowering of the load, and the swinging of the boom in either direction.

The frame of the swinging-gear annex is preferably made separable from the frame of the hoisting-engine proper, so that a hoisting-engine may be employed either without or with the annex, and therefore either as an ordinary hoisting-engine or as a complete derrick-engine. I have shown various forms for this construction. In Figs. 6 and 7 the swinging-gear frame consists of the pillow-blocks 28 29 and the connecting-ties 84 85, the pillow-blocks being provided with eyes 86 87,

adapted fordetachable connection with eyes 88 89 on the pillow-blocks of the hoisting-engine, In this case the hoisting-engine and the swinging gear are each self-con tained independently of each other. In the construction shown in Figs. 1 to 5 each pillow-block of the swinging gear is rigidly but detachably secured to a pillow-block of the hoisting-engine, so as to form a substantial extension thereof, this connection being made by the straps 90 and bolts 91 or 92. In Fig. 12 the pillow-block of the swinging frame is shown as non-detachable and integral with the hoisting-engine pillow-block.

The tandem arrangement of the hoistingdrum shafts 10 and 11, the swinging-clutch shaft 44, and the swinging-drum shaft 30 in the order named from the boiler at the rear to the front enables the hoisting-engine and swinging gears being constructed substantially as two units in the manner above set forth.

Although I have shown two swinging drums 81 32 controlling opposite ends of the bullwheel rope and so mounted that by the rotary adjustment of one or both slack in said rope may be taken up and have also shown them as mounted outside the pillow-blocks, I do not wish to limit myself in these respects, since the drum or drums need not be outside the pillow-blocks, and two drums are not necessary for the movement of said rope.

In Figs. 13 and Y14 is shown a third means of setting the clutch members. 93 is a sleeve having screw-threaded thereto a nut 94,'which is oscillated in the manner before described from shaft 57. This sleeve is enlarged at one .end, 95, and has keyed to it, as at 96, the bracket 97. ,A washer 98 is inserted between the end of the sleeve and a. shoulder on the shaft 44, which at this point is enlarged.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In combination with a hoisting-engine, a swinger-drum shaft located in front of said en- 1 gine, a swinger-drum thereon, a clutch-shaft located between said engine and said swingerdrum shaft and clutch mechanism on said clutch-shaft whereby said swinger-drum is controlled. 7 I
